Typical applications Transfer of corrosive liquids in the chemical industry and all aspects of
chemical engineering together with any application that requires the safeand economical transfer, or circulation, of acids and alkalis or otherchemical fluids, with or without solids in suspension. Construction features
1 Vertical centrifugal immersion pump for stationary application.The robust pump housing is solidly welded to the support tube.
A sleeve bearing specifications, which is lubricated by the liquid, allows immersion lengths
of up to 1000 mm, and on the pump size 230, with additional intermediatebearings, even up to 2000 mm.A large polpypropylene-coated drive shaft together with the use of a thick-walled support tube ensures a very smooth running pump.This type of construction prevents the rotating components from coming tocontact with the pump housing and guarantees a long service life and extended maintenance intervals, even in the case of continuous use.A range of carefully chosen impeller diameters, together with a range ofthree-phase motors in differing kW-ratings, ensures the optimum selection of pumps to meet the specific operating requirements. Connection of pump and motor is made via a flexible fitting.
